BICYCLE HANDLE-BAR,

SPECIFICATION forming part of Letters Patent No. 603,177, dated April26, 1898.

Application filed August 31, 1897. Serial No. 60,107. (NomOdeL) I To allwhom it may concern:

Be it known that I, AEDWARD EVELIN CROCKER, a citizen of the UnitedStates,"residing at McKenzie, in the county of Oarroll and State ofTennessee, have invented certain new and useful Improvements in BicycleHandle- Bars and I do herebydeclare the following to be afull, clear,and exact description of the invention, such as will enable othersskilled in the art 'to which it appertains to make and use the same.

This invention relates to improvements in bicycles, and has moreparticular relation to bicycle handle-bars of the adjustable type.

v The invention consists of thecombination, with a bicycle-head, of acasing mounted thereon, a handle-bar constructed of two movableconnected sections, a spring pressed looking-pawl for said sections, anda lever mounted on one of the handle-bar sections and connected to saidlooking-pawl.

The invention also consists of certain other novel constructionscombinations, and ar- 'rangements of parts, all of`which will behereinafter more particularly set forth and claimed.

In the' accompanying drawings, forming part of this specification,Figure l represents a perspective View of a head of a bicycle with myinvention applied ther-eto. Fig. 2 represents a central verticaltransversesection through the same, and Fig; 3 represents a horizontalsection through the containingcasing on the line of the locking-pawl.

1 in the drawings represents the head of the bicycle; 2, the containing-casin g mounted thereon; 3 3, the handle-bar sections; 4:, the

looking-pawl, and 5 the operating-handle; Said casing 2 comprises sideplates 6 6, connecting top and bottom cross-plates 7 7 ,which aresuitably bolted thereto, so that the interior of the casing may bereadily reached when so desired.

The -handle-bar sections 3 3 may be of any desired shape or conformationand are each provided. at' their inner ends with flattened v segmentalportions 8, formed on their periphwalls ofthe casing 2. One of thesegmental portions 8 is provided with a plurality of locking-apertures11, arranged in a concen'tric circle about its pivot and adapted to beengaged by a stud 12 of the looking-pawl 4. Said pawl 4 comprises a flatspring 13, secured at one end to the casing 2, so that its free end willform a yielding support for the stud 12, which latter passes through asuitable aperture formed in the casing 2, so as to enter any one of theapertures 11, as before stated, and thus lock the handle-bars in theirraised or lowered or any intermediate position. Sad pawl 4 is operatedby a bell-c'ank lever 14, jourualed in apertured lugs 15, mounted uponthe casing 2. Said bell-crank lever comprises a journal portion 16, acrank-bend 17, having aneye and attached at one end of said journalportion, and a plate or leaf 18, which latter projects under the freeend of the spring 13, so as to raise the same when' the journal portion16 is rotated. The crank-bend 17 is connected ,by a suitable cord orwire 19 to the operating-handle 5, which latter is pivotally mountedupon or near the end of one of the handle-bar sections, so as to occupya position where it may be readily grasped by the fingers.

I do not care to limit myself to the peculiar application of a cord orwire for connecting the bell-crank lever to the Operating-han dle, asany desired intermediate arrangement of levers or rods may be employedwith equal facility.

Itwill be observed from the foregoing description that it is notnecessary to stop the machine in order to raise or lower the handlebarsto the desired position, as the operation of the handle 5 willimmediately withdraw the stud 12 from the aperture 11, within which itis resting, and thus permit the handle-bars to be raised or lowered tothe desired position by the release of said handle.

IOO

mounted in said casing, one of them provided with a plurality ofopenings, a spring-pressed locking-pawl attached to the casing oppositcthe section having openings, an Operatinghzndle pivoted to the opposinghandle-bar section, and intermediate connections between theopcrating-handle and pawl, substantially as described.

In testimony Whereof I have signed this specification in the presence oftwo subscribing witnesses.
